--- Comment #8 from Ehsan Akhgari [:ehsan] <eh...@mozilla.com> ---
It turns out that the test case in comment 0 was completely wrong, sorry for
the red herring. Here is a minimized test case that demonstrates the
difference between cl and clang-cl:
$ cat test.cpp
namespace foo {
class __declspec(dllimport) S {
public:
static S* Instance() {
static S s;
return &s;
}
S() {}
};
}
void use() {
foo::S::Instance();
}
$ clang-cl -c -O1 test.cpp && llvm-nm test.obj
00000000 T ?use@@YAXXZ
00000001 a @feat.00
U __imp_??_B?1??Instance@S@foo@@SAPAV12@XZ@51
$ cl -nologo -c -O1 test.cpp && llvm-nm test.obj
test.cpp
00000000 T ?use@@YAXXZ
00e1797d a @comp.id
80000191 a @feat.00
U __imp_?Instance@S@foo@@SAPAV12@XZ
Note that if you drop the default ctor from S, or move S to the global
namespace, the bug goes away!
